Assume thаt we hаve а herd оf 50 hоrses and that we want tо select a random sample of 5 of the horses for an experiment. We begin at row 5 column 1 of a random number table and observe the random numbers shown in the table below. Col. 1 2 3 4 5 6 Row 5: 37570 39975 81837 16656 06121 91782 6: 77921 06907 11008 42751 27756 53498 Which one of the following is the correct set of 5 randomly selected horses to include in our experiment, assuming that we go from left to right across the rows of random numbers?
An оrnаmentаl hоrticulturist wаnts tо test the response of a variety of poinsettia plants to three rates of fertilizer application. He also includes a control in which the plants receive no fertilizer. He plants the poinsettias in three types of soil in pots in a greenhouse. The three types of soil represent three blocks in a randomized block design. After three weeks of growth in the greenhouse, he measures the height of the plants in inches. The data are shown in the table below. Soil type Fertilizer rate Loam Clay Sand Total None 24 16 14 54 Low 26 17 14 57 Medium 27 17 15 59 High 28 18 16 62 Totals 105 68 59 232 The partially completed Analysis of Variance table is shown below. What are the calculated F values for fertilizer rate and soil type?

Optiоn = D (fоr Prоf. Schwаrtz... disregаrd) Buccаneer Energy is a private electricity provider. Buccaneer has two electricity generation plants in the Tampa Bay area; each of which provides electricity service exclusively to a very large data warehouse and cloud computing customer (these sites require massive amounts of electricity to operate). Buccaneer is assessing the possibility of a malfunction of the generator at its 50 mega-watt Tampa, FL power plant. If a generator malfunctions, it needs to be manually restarted, which will cause an interruption of electricity service to the data warehouse customer utilized by that power plant = TB Data Inc. Based on the historical experience of the power plant, the Risk Manager was able to perform a quantitative analysis to derive the following information on the frequency of an interruption of electricity service in any given day, for the 50 mega-watt Tampa power plant: The probability of no service interruption in any given day = 75% The probability of a service interruption of 1 hour = 15% The probability of a service interruption of 2 hours = 9.5% The probability of a service interruption of 12 hours = 0.5% Per the terms of the exclusive service contract with TB Data Inc. = each hour there is an interruption of electricity service = $5,000 is taken off of that month's electricity bill. (i.e. = every hour there is a service interruption = $5,000 financial consequence for Buccaneer Energy) Part A: [3 points] From the perspective of Buccaneer Energy: calculate the Expected Value of the financial consequence from an interruption of electricity service to its customer TB Data Inc. (round to the nearest whole number!!!) (even though you are calculating a "loss" = keep your expected value calculation in POSTIVE numbers) (type your answer in number format = meaning no symbols ($), no decimals) ANSWER: Expected Value of the financial consequence from an interruption of electricity service for TB Data Inc. = [EXPVAL] Part B: [2 points] Based on the same historical experience of the Tampa power plant; the Risk Manager has also calculated the following in regard to the interruption of electricity service to TB Data Inc. The variance of the financial consequence from an interruption of electricity service to its customer TB Data Inc. = 27,248,400 Take the variance as FACT (you do NOT need to calculate it) From the perspective of Buccaneer Energy: calculate the Standard Deviation of the financial consequence from an interruption of electricity service to its customer TB Data Inc. (round to the nearest whole number!!!) (type your answer in number format = meaning no symbols ($), no decimals) ANSWER: Standard Deviation of the financial consequence from an interruption of electricity service to TB Data Inc. = [STDDEV] Part C: [5 points] Buccaneer has another large data warehouse client, located in St. Petersburg, FL: Pete Data Inc. Buccaneer also is assessing the possibility of a malfunction of the generator at its 60 mega-watt St. Petersburg, FL power plant. Just like the Tampa power plant, if a generator malfunctions, it will cause an interruption of electricity service to Pete Data Inc. The Risk Manager was able to perform a quantitative analysis to derive the following information for the St. Petersburg power plant: The Expected Value of the financial consequence from an interruption of electricity service to its customer Pete Data Inc. = $3,000 The Standard Deviation of the financial consequence from an interruption of electricity service to its customer Pete Data Inc. = $9,150 (Take these calculations as FACT... meaning you do NOT need to calculate them) The CEO of Buccaneer Energy wants to know which of these two power plants provides the most reliable service to its customer. In terms of the key measure of objective risk (the key measure of volatility) = which power plant, Tampa or St. Petersburg, faces more uncertainty in terms of financial consequence from an interruption of electricity service to its customer? (i.e. = which power plant should the CEO be more “uncertain” about its performance? Tampa? or St. Petersburg?) ANSWER for Tampa Power Plant: NUMERICAL VALUE for KEY Measure of Objective Risk = [COVTampa] (Round to TWO decimal places) (type your answer in number format = meaning no symbols ($), no commas) ANSWER for St. Petersburg Power Plant: NUMERICAL VALUE for KEY Measure of Objective Risk = [COVSTP] (Round to TWO decimal places) (type your answer in number format = meaning no symbols ($), no commas) FINAL ANSWER: Which power plant faces the MOST risk objectively, in terms of the financial consequence from an interruption of electricity service to its customer? = [FINALANSWER] Simply type the NUMBER (1, 2, 3, or 4) of your choice: Tampa Power Plant St. Petersburg Power Plant Tampa Power Plant and St. Petersburg Power Plant face the same amount of risk objectively Cannot be determined
